Sorry - I'm so used to these things that I just mentally edited out the
extra ones. Yes, NC does indeed mean "no connection".
All you need for the most basic serial connection are the three wires
which are common to both - two for data and one for ground. Whether you
then need the others depends on what type of flow control you are using.
You say your existing cable doesn't work. Have you wired up just the
three connections or all of them?
